This is a program I wrote in Processing (a collection of graphics libraries and an IDE for java).  For this program, I had to implement a matrix stack and a library for matrix and vector math.  I then had to use that library to transform and project input provided for the assignment.  When run, the program processes the inputs and displays the results.
